Description
The STNRGPF02/12 embed the Inrush Current Limiter function.
STNRGPF12 features a digital inrush current control generating two PWM’s signals
in order to drives the input semi-controlled bridge.
STNRGPF02 embeds inrush current control function setting high a signal that is used
to short a resistive element.
